CAR-AXLE.

SPEC FICATION forming part of LettersBatent No. 284,194, dated September 4, 1883.

7 Application filed March 19,1883, (Ila model.)

tral and end disks, connected by bars and arrangedwith a bearing in the central disk to supportthe meeting ends of the axle, and with bearings in the end disks to furnish supports for the axle near the inner faces of the'wheels,

which are secured upon the respective halves of the axle.

In said drawings, Figure 1 is a side elevation, showing my invention as applied to a caraxle, upon which are mounted the wheels. Fig. 2 is a longitudinal vertical sectionpf the parts shown in Fig. 1. Fig. 3 is a vertical transverse section taken on line 00 m, Fig. 1, and as looking to the right in said figure.

wheels, in which are respectively secured, in the usual manner, the axle b, which is formed in two equal lengths, as shown in Fig. 2, and

in the usual manner, said several parts being old, common, and well known. 3 I

For the purpose of holding the inner ends of the axle in line and furnishing journal-boxes therefor, I provide my bearing-truss, formed, as shown, in two sections orlengths,each section consisting of alarge'r disk, d,and smaller disk, e, the two being united by bars j, which are arranged around the periphery of said disks, as shown, said two larger disks being rigidly bolted together, asshown at h, so that the two sections, for all practical purposes, c onstitute a rigid truss, as if formed entire, instead of in two sections or parts. The bars f and disks d e, at the respective ends thereof, are preferably formed, as an entirety, of malleable iron or other suitable metal, and said bars f may be formed either solid or hollow, both which forms are shown in the-drawings. Said end disks, e, are formed with an inwardly-projecting flange, as shown, in which I secure a sleeve, 9, of some anti-friction metal, to serve as bearings for the axle, and the collars p, secured on the axle by set-screws, as shown, abut against said sleeves g andthe flange in which they are secured, and in the central disks, d, I secure a sleeve, i, of suitablemetal, to serve as the bearing of the axle, said sleeve having a series of transverse holes, j, through'which the oil held by packing is, seated in an annular chamber in disks d, can pass into said sleeve and lubricate the axle therein rotating, passages I being provided in said flanges, by which packing is can be removed, replaced, or increased, and a radial compressive, according as. said rods may be above or below the axle, and hence the rods are capable of sustaining a greater strain than if arranged parallel with the-axle. In said views, a (0 represent a pair of carhalves of the axle will cause a corresponding rotary movement thereof in the bearings in the truss.

For the purpose of protecting the bearings in my truss from grit and dust, I arrange a sleeve, n, in two sections, each of which, at its respective ends, is seated upon the flanges of disks d c, as shown,which holds the sleeve centrally in position. Said sleeves are preferably formed of india-rubber or other flexible material. y

I am aware that many devices have been invented and patented having for their object the securing an independent rotary movement of each wheel on thesame car-axle, and hence I make no broad claim thereto; and Iam also aware of the United States Patents No. 47,015,

granted March 28, 1865, to J. W. Hard, and No. 48,114, granted June 6, 1865, to 'Iibbetts and Merriel, and I make no claim to what is therein described and shown, my invention be- 5 ing unlike that shown in either of said patents.

I claim as my invention- 1. An axle-supporting truss formed in two sections, united as specified, each section being formed with a larger disk, (1, and a smaller I 0 disk, 6, united by means of supports f, arranged at or near theperipheries of the disks, and constituting therewith an entire and unitary casting, and provided with axle-bearings, substan-. tially as specified.

2. In combination with divided axle b and 15 the bearing truss, formed substantially as shown, the sleeves n, mounted upon and held centrally in position by the projecting concentric flanges of disks d e, substantially as speci-
